Level 2 Electrical Diploma (City & Guilds 2365-02)
The Level 2 Electrical Diploma (City & Guilds 2365-02) qualification is the starting point for most new entrants who want to become electricians without an apprenticeship in place. It gives you the core theory and practical skills you need to move safely and confidently into junior site roles or progress on to Level 3.
At Logic4training, the City & Guilds 2365 Level 2 Electrical course is delivered in modern training centres in Northolt, Basildon, Luton and Sittingbourne, combining classroom teaching with hands-on workshop time. The qualification is formally titled “City & Guilds Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02)”.
What you will learn at Level 2
The Level 2 focuses on electrical foundations: safety, basic science, simple circuits and standard domestic/commercial wiring methods. While individual units are set by City & Guilds, they typically include:
- Health and safety in building services engineering, including safe isolation, PPE and risk assessment.
- Electrical installation technology, such as cable types, accessories, containment systems, and how different wiring systems are used.
- Electrical installation methods, including basic circuit installation, terminations, and connection of common equipment.
- Electrical science and principles, covering voltage, current, resistance, power and how they apply to real circuits.
- Understanding drawings, symbols and basic design concepts for simple installations.
You can expect a mix of written exams, online tests and practical assessments that check your knowledge and your ability to work safely with tools, test instruments and real circuits.
Who is the Level 2 2365 for?
The 2365 City & Guilds Level 2 Electrical Diploma is designed for:
- New entrants with little or no electrical experience who want a recognised qualification.
- Career changers moving from other trades (for example, plumbing, maintenance, armed forces).
- Learners aiming to build towards the full 2365 Level 2 & 3 route, then the 2357 City & Guilds NVQ.
At Logic4training, we recommend the Level 2 as the natural first step if you know you want to work as an electrician but do not yet have an employer to sponsor a formal apprenticeship.
Level 3 Electrical Diploma (City & Guilds 2365-03)
The Level 3 Electrical Diploma (City & Guilds 2365-03) qualification builds on your Level 2 knowledge with more advanced theory, design and testing, and is a key milestone on the journey to becoming a fully qualified electrician. It prepares you for higher responsibility on site, more complex installations and the next step into the 2357 City & Guilds Level 3 NVQ.
Logic4training delivers the City & Guilds 2365 Level 3 Electrical course as an intensive programme at its centres, taught by experienced electricians and assessors who understand how the qualification translates into real‑world work.
What you will learn at Level 3
At Level 3, the content moves beyond basic circuits into design, fault finding and verification of full electrical systems. Typical areas covered include:
- Advanced electrical science and principles, including three‑phase systems, power factor and more complex calculations.
- Design, installation and verification of electrical installations across domestic, commercial and light industrial environments.
- Diagnosing and correcting electrical faults using systematic test and inspection techniques.
- Inspection, testing, commissioning and certification of electrical installations in line with wiring regulations.
- Organising work, supervising others, and planning installations to meet client and regulatory requirements.
Assessments typically include written exams, online tests, practical assignments and a more demanding inspection and testing element than at Level 2. You will be expected to interpret regulations, apply calculations and justify your design decisions as part of your practical tasks.
Entry requirements and progression
To join the Level 3 Electrical Diploma (2365-03) you will normally need to have already achieved the 2365-02 Level 2 Electrical Diploma or an equivalent Level 2 technical qualification. This ensures you have the foundations to cope with the higher‑level theory and more complex assessments.
Completion of Level 3 is a key requirement before progressing to the City & Guilds 2357 Level 3 Electrical NVQ. Together, 2365-02, 2365-03 and 2357 form the most common modern route to achieving your ECS Gold Card as a fully qualified electrician.
City & Guilds 2357 Level 3 Electrical NVQ
The City & Guilds 2357 Level 3 Electrical NVQ qualification is the work‑based qualification that proves you can apply your Level 2 and Level 3 diploma knowledge safely and independently on real jobs. It is one of the final steps on the journey to becoming a fully qualified electrician and applying for your ECS Gold Card.
Logic4training delivers the C&G 2357 Level 3 Electrical NVQ in Electrical course as a portfolio‑based, on‑site assessment programme, with expert NVQ assessors supporting you from enrolment through to AM2.
What will you do on the 2357 NVQ
Unlike the classroom‑based 2365 diplomas, the 2357 NVQ is completed while you are working in the industry, gathering evidence from real installations you are involved in. Typical activities and performance areas include:
- Applying health and safety legislation and safe working practices on site, including safe isolation and risk assessment.
- Planning, preparing and installing wiring systems and associated equipment in buildings, structures and the wider environment.
- Overseeing and organising the work environment, coordinating with other trades and maintaining documentation.
- Commissioning, inspecting, testing and fault‑finding on installed electrical systems in line with BS 7671 and employer procedures.
- Demonstrating your ability to work to drawings, specifications and client requirements across a range of real projects.
Evidence is normally collected through methods such as site photographs, reflective accounts, witness testimonies from supervisors, and at least one direct on‑site observation visit from a Logic4training assessor.
Assessments, AM2 and the ECS Gold Card
During the 2357 NVQ you will build an e‑portfolio that maps your site evidence against the City & Guilds performance units. Once your assessor is satisfied that you meet all requirements, you will be signed off as having completed the NVQ and can move on to your AM2.
The AM2 (or AM2S/AM2E, depending on your route) is an independent, practical end‑point assessment in Level 3 NVQs where you install, inspect, test and fault‑find on a full electrical installation under exam conditions. Passing both the 2357 NVQ and the AM2 is a key requirement for applying for your ECS Gold Card, which is widely recognised across the UK as proof that you are a fully qualified electrician.
Entry requirements and progression
To enrol on the 2357 NVQ, you must already be working in the industry in a role that gives you access to a suitable range of installation work. You will also normally need to hold a suitable technical qualification, such as the City & Guilds 2365 Level 2 and Level 3 Electrical Diplomas, so that you have the underpinning knowledge to support your on‑site decisions.
Completing the 2357 City & Guilds NVQ, alongside your 2365 diplomas, 18th Edition and AM2, positions you to join a Competent Person Scheme and work across domestic, commercial and industrial installations as a fully qualified electrician.
How 2365 and 2357 work together
Both 2365-03 City & Guilds and 2357 City & Guilds sit at Level 3, but they play very different roles at different stages of your career. They work together as a pathway. 2365 gives you structured technical knowledge and practical skills in a training centre, while 2357 proves you can apply that learning independently on real sites to industry standards.
Think of 2365 as the learning stage, controlled environment, set tasks, mock installations, and 2357 as the on‑the‑job proof that you can do the same work under real‑world pressure with real customers and deadlines.
In practice, many learners follow a route that looks like this, with each step building on the last.
1. Complete City & Guilds 2365 Level 2 Electrical Diploma
At this stage you are learning electrical fundamentals in the classroom and workshop – basic circuits, safe isolation, tools and materials, simple testing. You are not yet expected to lead work on site, but you are starting to understand how real installations go together.
2. Progress to City & Guilds 2365 Level 3 Electrical Diploma
Level 3 pushes you into more complex design, fault‑finding and inspection and testing so you can take on more responsibility when you get into the workplace. You will be working to wiring regulations, designing circuits on paper, then installing and testing them in a controlled environment.
3. Gain employment in the electrical industry
Once you have your Level 3 Electrical Diploma, the priority is to secure a role where you are hands‑on: installing, maintaining or testing electrical systems under the supervision of a qualified electrician. This could be with a small domestic contractor, a larger commercial firm or a maintenance team.
4. Enrol on the City & Guilds 2357 Level 3 Electrical NVQ and build your on‑site portfolio
With suitable work in place, you move onto the 2357 NVQ, which is a portfolio‑based, work‑based qualification. Over time you collect:
- Photographic evidence of installations you have worked on.
- Copies of certificates, test results and job documents you have helped complete.
- Short written reflections explaining what you did, why you did it that way, and how you met safety and regulatory requirements.
- Witness testimonies from supervisors or colleagues confirming your role on specific jobs.
- At least one direct on‑site observation from a Logic4training assessor, who will watch you work, ask questions and confirm your competence.
Logic4training supports this with an online e‑portfolio system, clear guidance on the evidence you need, and check‑ins to keep you on track. For most learners, this is the stage where they really start to feel like a working electrician rather than a student.
5. Pass the AM2 assessment & apply for your ECS Gold Card.
When your 2357 NVQ portfolio is signed off, the next step is the AM2 (or AM2S/AM2E depending on your route), known as the final, independent practical assessment, where you install, inspect, test and fault‑find on a full rig under exam conditions. Passing both the NVQ and AM2, alongside your 2365 diplomas and 18th Edition, gives you the qualification package required to apply for your ECS Gold Card.
The ECS Gold Card is widely recognised as proof that you are a fully qualified electrician and allows you to work unsupervised on most UK sites. We explain this whole journey, including timescales and package options, in our guide How to become an electrician in the UK.
Summary: choosing the right electrical route
If you want to become a fully qualified electrician via the diploma route, you will usually complete a Level 2 Electrical Diploma, a Level 3 Electrical Diploma, the City & Guilds 2357 NVQ and the AM2, before applying for your ECS Gold Card. Together, these steps take you from learning the basics in a training centre to proving your competence on real‑world installations and working unsupervised on site.
City & Guilds 2365 Level 2 and Level 3 give you the structured theory and practical skills you need, while the 2357 NVQ and AM2 provide the on‑site evidence and final assessment that employers and schemes look for.
